PLANER FEED ATTACHMENT.

Patented Nov. 5, 1912.

Application filed September 1.1, 1 911. Serial No. 648,752.

To all whom it may concern:

Be it known that 1, PETER J. J ononnn, a citizen of the United States,and resident of Sheboygan Falls, in the county of Sheboygan and State ofWisconsin, have invented new and useful Improvements in Planer FeedAttachments, of which the followmg is a description, reference being hadto the accompanying drawings, which are a part of this specification.

This invention has for its object to provide an attachment for undercutplaners which will serve the purpose of a feedlng mechanism such asshown in my Letters Patent No. 908,269, dated December 29, 1908, andwhich will be capable of being quickly moved out of its operativeposition so as to clear the tablewhen it is desired to feed work byhand.

Another object of this invention is to improve upon details of.construction of such attachment, whereby it maybe applied to any planertable without havlng to fit parts or to make alterations therein, andwhereby the shifting of the attachment from its operative position toits inoperative posit on may be accomplished without disconnecting thedriving mechanism therefor.

With the above and other objects in view the invention consists in thefeeder attachment for planers as herein claimed and all equivalents.

Referring to the accompanymg drawlngs in which like characters ofreference indicate the same parts in the different views: Figure 1 is arear elevation of a planer having the feed attachment of this inventionapplied thereto in its operative position; Fig. 2 is an end viewthereof; Fig. 3 is a plan view thereof, the inoperative position of theattachment being shown in dotted lines; Fig. 1 is a longitudinalsectional view of the supporting post of the attachment and the driv ingand adjusting mechanism therein, being taken on the plane of line 4.4 ofFig. 8; Fig. 5 is a sectional plan view on the plane of line 5-5 of Fig.2; and Fig. 6 is a transverse sectional view through the feed mechanismon the plane of line 6-6 of Fig. 3.

In these drawings 10 indicates the base of an ordinary undercut planerand 11 is the table thereof, beneath which the usual cutter 12- isdriven by a belt pulley 13 in the well known manner. Details ofconstruction of the planer have not been shown as the attachmentconstituting this invention applicable to any type of planerconstruction.

A pedestal 14 is adapted to be secured to the floor alongside of theplaner, at the rear thereof, as shown, and, as will be most clearly seenin Fig. 4, this pedestal comprises a vertical tubular column or standard15, which is telescoped by a tubular sleeve 16 carrying a head 17. Thesleeve 16 is adjustable on the column 15 as the closed upper end thereofrests on a ball bearing which is seated on a shoulder 19 of a verticalscrew rod 20 which is threaded at its lower end in a block 21 fitting inopenings through the base of the column, said screw rod extendingthrough the top of the sleeve and being provided with a hand wheel 22 bymeans of which it may be turned. The turning of the hand wheel 22threads the rod 20 through the nut formed by the block 21 and so liftsor lowers the sleeve 16 and the parts carried by it.

A pair of parallel horizontal bars 23 pass through openings provided forthem in the head 17 and together with said head and an end plate 24connecting them at their outer ends form a rectangular frame for thesev- .eral driving units, of which there may be any number, according tothe width of the planer table. A driving shaft 25 extends the fulllength of the attachment frame, being journaled in the end plate 24 atone end and in the head 17 at the other end, where it enters the upperend of the sleeve 16 to receive its driving connection to be laterreferred to. As best seen in Figs. 3 and 6, this driving shaft 25 formsa pivotal support for a number of swinging frames 26, each carrying aheavy feed roll 27 with sprocket teeth 28 formed thereon, which areconnected by a chain 29 with a sprocket wheel 30 keyed on the driveshaft 25. Thus the frames 26 are free toswing on the shaft 25 and thefeed rolls 27 are positively driven from the shaft 25 while the swingingmovement of the frame is limited by the outer end thereof en 'aging oneof the bars 23. The feed rolls 2 are in this manner mounted to yieldvertically so as to engage lumber of different thickness, and they aretoothed or roughened to engage the lumber and force it over the cutter.The adjustment of the attachment by turning the hand wheel 22 is made tolift the attachment frame to the desired distance above the table topermit the lumber to pass beneath it. 7

A bevel gear 31 on the drive shaft 25 within sleeve 16 meshes with abevel gear 32 on the upper end of a sleeve 33 which surrounds the screwrod 20 and is supported in a bearing 34 within the sleeve 16 and abearing 35 within the column 15. Between the bearing 35 and anotherbearing 36 formed in the column, there is a worm wheel 37 which is heldin place by its engagement with these hearings and which is splined onsleeve 33 so as to maintain its drive connection therewith in anyvertical adjustment of the attachment. The column 15 forms a housing 38on one side thereof between the bearings 35 and 36 for containing a worm39 meshing with the worm wheel 37, and said worm is keyed on acountershaft 40 which is journaled in babbitted bearing plates 41 and 42which close the ends of the housing 38. A cone pulley 43 is looselymounted on the end of shaft 40 and is provided with clutch teeth 44 tobe engaged by a clutch member 45 which is splined on the shaft 40 and isthrown into or out of engagement by a yoke 46 pivotally mounted on abracket 47 extending from hearing plate 41. A clutch rod 48 is securedto the yoke 46 so that by turning it the clutch may be thrown into orout of its driving engagement.

In operation the feeder attachment is swung to its position over thetable, the sleeve 16 freely turning upon column 15 for this purpose. Theattachment is then adjusted to the proper elevation by turning the handwheel 22 and the outer end of the frame of the attachment is thendesirably fastened in position by means of a hand screw 49 carried by abracket 50 on the end plate 24 threading into the upper end of a strap51 which is secured to the frame of the planer. The bracket 50 isslidable in ways on the end plate 24 and is held by a set screw 52 so asto allow for the adjustments of the attachment frame above the table. Itis then only necessary to throw the clutch to its engaged position bymeans of the clutch rod 48, when all of the feed rolls are set in motionthrough the driving connection comprising the shaft 40, the engaged worm39 and the worm wheel 37, the sleeve 33, the engaged beveled gears 32and 31, the shaft 25 and the chain connections therefrom to the feedrolls.

When it is desired to feed work by hand the attachment is released byremoving the hand screw 49 and is swung to the back of the table, asshown by dotted lines in Fig. 3, where it is out of the way, and thismovement of the attachment to its inoperative position, as well as thevertical adjustment thereof, may be accomplished without hindrance bythe driving connections.

hat I claim as new and desire to secure by Letters Patent, is:

1. A feed attachment for planers or the like, comprising a standard, asleeve telescoping therewith, a frame carried by the sleeve, a shaftmounted on the frame, feed rolls carried by the frame and driven fromthe shaft, a screw rod extending through the sleeve, a nut on thestandard in which the screw rod is threaded, said sleeve havingengagement with the screw rod to he supported thereby, means for turningthe screw rod, a sleeve surrounding the screw rod, a bevel pinionthereon, a bevel pinion on the shaft meshing therewith, a worm gearsplined on the sleeve which carries the bevel pinion, a countershaftjournaled in the standard, a worm on the counter-shaftmeshing with theworm gear, and means for turning the countershaft.

2. A feed attachment for planers or the like, comprising a tubularstandard adapted to be positioned at the side of'a planer, a

sleeve telescoping the upper end thereof, a

head on the upper end of the sleeve, horizontal bars extending from thehead parallel with relation to each other, an end plate connecting theends of the horizontal bars, a shaft journaled in the end plate and thehead of the sleeve, frames pivotally mounted on the shaft, feed rollscarried by the frames, sprockets on the shaft, driving chains connectingthe sprockets with the feed rolls, a bracket adjustably mounted on theend plate, a strap adapted to be secured to the planer, a clamping screwconnecting the bracket with the strap, a shouldered screw rod extendingthrough the sleeve and standard, a nut block fitting in openings of thestandard and having the screw rod threaded therein, the head of thesleeve bearing on the shoulder of the screw rod, a hand wheel'on thescrew rod above the head of the sleeve by which the screw rod may beturned by adjusting the elevation of the sleeve, a driving sleevesurrounding the screw rod, intermeshing beveled gear wheels on the shaftand the driving sleeve respectively, a worm gear splined on-the drivingsleeve, a worm housing within the standard and meshing with the wormgear, a countershaft journaled through the worm housing of the standardand having the worm keyed thereon, and a clutch pulley drivingconnection on the countershaft.
